xcmJobStartedProcessingTime
1.3.6.1.4.1.253.8.59.16.1.1.4
The time at which the job started to be processed by the
intended device (printed, scanned, faxed, etc.).
NOTE: For use with this MIB, this attribute has been generalized
to be used with any device, whereas the corresponding ISO DPA
attribute is only started printing.
A conforming implementation shall return an actual date and
time, rather than the DEFVAL, unless the implementation cannot
tell time.
ISO DPA: Started-printing-time
This attribute indicates the time at which this job started
printing [processing].
